Yixin Wang

I am a 3rd year Ph.D. student at Stanford University, working on AI + Healthcare.
I am fortunate to be co-advised by Dr. Kilian M. Pohl and Dr. Michael Zeineh.

Before starting my Ph.D., I got my master degree from Institute of Computing Technology, Chinese Academy of Sciences, majoring in Computer Science, supervised by Prof. Zhiqiang George He (Senior Vice President, Lenovo). Since Sept.2019, I have been an intern in AI Lab, Lenovo research, advised by Dr. Jianping Fan (Lenovo VP, Head of AI Lab) and Dr. Yong Rui (Fellow of ACM, IEEE, AAAS, IAPR, SPIE). Before that, I received B.Eng in Computer Science and Technology from Shandong University in 2019.

Research

Multi-Modal Analysis

    Medical databases include abundant information formats, such as imaging, texts, tabular data, and signals. Specifically, in medical imaging, there are different modalities such as MRI, CT, X-ray, PET, and so on. Different modalities are chosen to provide anatomical and functional information about organ and tissue structure. We design a Modality-Pairing Network to effectively capture the complementary information from multiple MRI modalities for brain tumor segmentation (MICCAI BraTS challenge 3rd prize)[PDF][Code]. We further focus on the challenging issue of missing modalities and propose an ACN network to enable a coupled learning process to enhance the learning ability of both full modalities and unimodal training [PDF][Code]. Besides, we explore the power of text & image in medical diagnosis. We explicitly quantify both the visual uncertainty and the textual uncertainty for DL-based medical report generation (MRG)[PDF]. We also establish a complete knowledge graph (KG) on chest X-ray imaging to address the long-tailed problem of disease distribution in current MRG datasets [PDF][Code].

Data-efficient Learning

    DL methods in medical imaging require high-quality annotated data for training and validation. However, obtaining perfectly labeled datasets in the medical domain is challenging. These problems can be addressed by 1) maximizing the benefit of existed labeled data or 2) leveraging the unlabeled data. To better utilize the unlabeled data, we developed a semi-supervised learning method which utilizes a teacher-student model to take advantage of unlabeled data [PDF]. While training a deep learning models with extremely limited labeled dataset, the model is easily running into over-parameterization. To tackle this issue, we further propose a Transfer learning (TL) framework where a Hybrid-encoder strategy based on multi-lesion pre-trained model to enhance model’s generalization for segmenting COVID-19 infection [PDF]. Due to the limited data sets, our knowledge about data (environment) & learning tasks could be incomplete at the training time. We do expect our AI system can learn to know unknowns (e.g., new disease) adaptively. Therefore, we design a novel cross-domain few-shot learning techniques, leveraging the power of natural data sets for rare skin disease segmentation [PDF].
